I just looked up the owner's manual for a 2022 Quietech and see the Available Viscosity Index on page 20 showing 10W30 & 10W40. This chart is not in my 2014 or 2018 manuals. Both manuals list only 10W30 in multiple places.
The emission control label on the frame near the engine on the 2022 says 10W30 according to the manual.
